Would Kristen Stewart ever consider quitting acting and opt for a quiet life outside of the spotlight?

Don't worry Twi-hards, because it doesn't sound like it.

"Oh man, I really love my job," Stewart told us at last night's NYC premiere of On the Roadwhen asked about leaving Hollywood behind post-Twilight. "I would not give it up."

Now that K.Stew's movie-making future is secure, let's talk about what really matters—the 22-year-old actress' plans to spend Christmas with her boyfriend Robert Pattinson!

A source tells E! News that Stewart left NYC earlier today to return to L.A. for the holidays with R.Pattz. The couple will spend Christmas and New Year's together until he leaves on Jan. 8 to start filming his next project.

Meanwhile, Stewart was nothing but happy (sans Pattinson) while celebrating her new flick at last night's On the Road premiere afterparty at NYC hot spot the Boom Boom Room.

"She was in great spirits and was in a really good mood," a source says. "She is so happy about this film."

Stewart hung out at the bash with costars Kirsten Dunst and Garrett Hedlund for about two hours before leaving to get ready to return to L.A.
